General Power Tool Safety Warnings
WARNING! Read all safety warnings and
instructions. Failure to follow the warnings and
instructions may result in electric shock, re, and/or
serious injury.
Work Area Safety
► Keep your work area clean and well lit. Cluttered or dark work
areas invite accidents.
► Do not operate power tools in explosive atmospheres, such
as in the presence of ammable liquids, gases, or dust. Power
Electrical Safety
► Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with earthed
(grounded) power tools. Unmodied plugs and matching
outlets will reduce risk of electric shock.
► Avoid body contact with earthed or grounded surfaces such
as pipes, radiators, ranges and refrigerators. There is an
increased risk of electric shock if your body is earthed or
grounded.
► Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
► Do not abuse the cord. Never use the cord for carrying, pull-
ing, or unplugging the power tool. Keep cord away from heat,
oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
► When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord for outdoor use
reduces the risk of electric shock.
Save all warnings and instructions
for future reference.
tools create sparks which may ignite the dust or fumes.
► Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
► If operating a power tool in a damp location is unavoidable,
use a ground fault circuit interrupter (GFCI) protected supply.
Use of a GFCI reduces the risk of electric shock.
► Never use an extension cord that is damaged, including cuts,
exposed wires, or bent/missing prongs. Damaged extension
cords increase the risk of re or electric shock.
► Use only extension cords rated for the purpose.
► Use only extension cords rated for the amperage of this tool
and the length of the cord. Using too small of an extension
cord can cause the cord to overheat.

Personal Safety
► Stay alert, watch what you are doing, and use common sense
when operating a power tool. Do not use a power tool while
tired or under the inuence of drugs, alcohol, or medication.
A moment of inattention while operating power tools may
result in serious personal injury.
► Use personal protective equipment. Always wear eye pro-
tection. Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
► Prevent unintentional starting. Ensure the switch is in the
off-position before connecting to power source, picking up,
or carrying the tool. Carrying power tools with your nger on
the switch or energizing power tools that have the switch on
invites accidents.
► Remove adjusting key or wrench before turning the power
Power Tool Use and Care
► Do not force the power tool. Use the correct power tool for
your application. The correct power tool will do the job better
and safer at the rate for which it is designed.
► Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
► Disconnect the plug from the power source before making
any adjustments, changing accessories, or storing the tool.
Such preventive safety measures reduce the risk of starting
tool on. A wrench or a key that is left attached to a rotating
part of the tool may result in personal injury.
► Do not overreach. Keep proper footing and balance at all
times. This enables better control of the tool in unexpected
situations.
► Dress properly. Do not wear loose clothing or jewelry. Keep
your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
► If devices are provided for the connection of dust extrac-
tion and collection facilities, ensure these are connected and
properly used. Use of dust collection can reduce dust-related
hazards.
► Always wear safety glasses complying with ANSI Z87.1.
Ordinary glasses are not proper protection.
the tool accidentally.
► Store idle tools out of reach of children and do not allow
persons unfamiliar with the power tool or these instructions
to operate the power tool. Power tools are dangerous in the
hands of untrained users.
► Maintain power tools. Check for misalignment or binding of
moving parts, breakage of parts and any other condition that
may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by

poorly maintained power tools.
► Keep cutting tools sharp and clean. Properly maintained tools
with sharp cutting edges are less likely to bind and are easier
to control.
► Use the power tool, accessories, and tool bits etc. in accor-
Service
► Have your power tool serviced by a qualied repair person
using only identical replacement parts. This will ensure that
Specic Safety Rules for Tenon Joiners
► Mortising bits must be rated for at least the speed recom-
mended on the tool. Mortising bits running over rated speed
can y apart and cause injury.
► Always use the fence. The fence protects the operator from
unintentional contact with the mortising bit. When the fence
is removed from the joiner, the spinning and oscillating cutter
is exposed and can cause serious injury.
► Keep hands away from the cutting area. Never place your
hand on the front face of the fence while the tool is running.
► Use only Festool authorized mortising bits. Non-approved
mortising bits can come loose during operation.
► Never use dull or damaged mortising bits. Dull or damaged
dance with these instructions, taking into account the working
conditions and the work to be performed. Use of the power
tool for operations different from those intended could result
in a hazardous situation.
► To reduce the risk of serious injury, never alter or misuse the
power tool.
the safety of the power tool is maintained.
mortising bits can cause the tool to lurch sideways unexpectedly and lead to a loss of control of the power tool.
► Do not operate the tool if the spring-loaded fence does not
return to its forward rest position. The fence covers the mortising bit and prevents accidental contact. If the slides of the
fence do not move freely, have the tool serviced immediately.
► Wait for the cutter to stop before setting the tool down. An
exposed cutter may engage the surface leading to possible
loss of control and serious injury.
► Use clamps or other practical way to secure and support the
workpiece to a stable platform. Holding the work by hand or
against your body is unstable and may lead to loss of control.
Respiratory Exposure Safety Warnings
► Substantial or repeated inhalation of dust and other airborne
contaminants, in particular those with a smaller particle
size, may cause respiratory or other illnesses. Various dusts
created by power sanding, sawing, grinding, drilling and other
construction activities contain chemicals or substances known
(to the State of California and others) to cause cancer, birth
defects or other reproductive harm. Some examples of these
chemicals/substances are:
► lead from lead-based paints;
► crystalline silica from bricks, cement, and other masonry
products;

The Domino DF 700 Tenon Joiner is used to cut mortises in
wood for oating tenon joinery. Mortise and tenon joinery
is one of the oldest and strongest methods of joining pieces
of wood together. The Domino tenon joiner greatly simpli-
es the task of cutting mating mortises in workpieces to be
connected together. A rotating and oscillating cutter sweeps
across the workpiece to quickly and effortlessly cut a uniform mortise, in which a Domino oating tenon is inserted.

Setting Up a New Domino Joiner
Congratulations on your purchase of a new Festool Domino
Tenon Joiner. The Domino joiner is the nest portable loose
tenon joiner in the world. Before using your new Domino
joiner, make sure you fully read and understand all of
the precautions and safety information presented in this
manual.
WARNING! To reduce the risk of injury from contact
with a moving part, always unplug the joiner before
making any inspections or adjustments, or before
installing or removing any accessory!
1. With the joiner unplugged, inspect the mortising bit.
Make sure it is not bent, chipped, or otherwise damaged,
and make sure the bit is fully tightened on the spindle.
(Refer to “Changing the Mortising Bit” on page 9 for
more information).
CAUTION! Check regularly whether the mortising
bit is in good condition. Mortising bits that are bent
or damaged can break, and should no longer be
used.
2. Peel off the protective lm from the bottom of the joiner
baseplate.
3. Set up the joiner for the appropriate type of operation as
described throughout the remainder of this section.
4. Make sure that the fence height and angle locking levers
are properly tightened.
5. Install the power cord into the Plug-It receptacle on the
joiner (refer to page 10 for more information).
6. Before you use the joiner, make sure to read the
”Overview, General Notes, and Tips” on page 10.
Setting the Fence Angle
Some joints require the fence to be set to an angle from the
mortising bit. The most common application is for making a
mitered joint (see page 16).
1. Unplug the joiner for safety.
2. Loosen the fence angle locking lever by rotating it counterclockwise about ¼-turn.
3. Rotate the fence face to the desired angle, and tighten
the locking lever.
Notes:
► The fence has detent stops at 22½, 45, 67½, and 90
degrees.
► Use the gauge pointer for setting the fence to angles other
than the ones listed above.
► For greater stability, the locking lever clamps down on
both right and left sides of the fence.
The table below provides some common miter angles for
easy reference.

Indicator
The height of the fence needs to be adjusted depending on
the type of joint being made and the thickness of the mate-
rial being joined. Refer to the ”Applications” section begin-
ning on page 13 for more information about the optimal
fence height for the specic application. There are two
features available for setting the fence height; the height
gauge and the height stop.
Note: It is not necessary to set the mortise height to
be exactly in the center of a board. Attempting to do
so can be difcult, and may actually lead to assembly
errors. It is more important to always ensure that the
same surface is referenced for each workpiece.
Height Stop
The height stop provides quick access to repeatable height
settings. This can be especially benecial in applications
where you need to continually change the fence height from
one mortise to another, such as an offset joint with a reveal
between the pieces.
Height Gauge
The height gauge shows the distance between the bottom
of the fence face and the centerline of the mortising bit. Use
this gauge to set the mortise height relative to the surface
of the workpiece.
b. Slide the stop in or out until the desired setting (in
mm) is shown in the window.
c. Lower the fence down until it touches the stop.
d. Tighten the locking lever.
3. To use the height gauge:
a. Make sure the Height Stop is retracted out of the way.
b. Raise or lower the fence until the pointer is pointing to
the desired height on the gauge.
c. Tighten the locking lever.
Note: Make sure to retract the Height Stop to its
lowest setting when using the Height Gauge.
Setting the height
1. Loosen the fence height locking lever by turning it ¼-turn
counterclockwise.
2. To use the Height Stop:
a. Raise the fence above the desired setting.
Setting the Mortise Width
The width of the mortise slot can be increased to permit
some side-to-side exibility in the tenon position. The mortise width lever has two positions. In the standard position,
the Domino tenon will t snugly into the mortise slot. In the
wide position, the mortise slot will be 3 mm wider than the
Domino tenon.
NOTICE: Never rotate the dial during a plunging
operation. This can bend or break the mortising bit,
and can also damage the machine.

The mortising depth determines how deep into the work-
piece the mortising bit penetrates. This needs to be adjusted
for different sized tenons. In most cases, the tenon should
be centered across the joint, and the depth of the mortise
should be ½ the length of the tenon. However, in some
cases you may want to have more of the tenon in one piece
than the other (lower Domino tenon pictured below). In this
case, the sum of the two depths must equal the length of
the tenon. (In the offset tenon example below, the Domino
tenon is 50 mm long, the left mortise is 35 mm deep, and
the right mortise is 15 mm deep.)

If you are frequently switching depth settings, use the two
limit stops to assist in setting those positions. This is also
helpful when working with thin materials and you set the
maximum limit to be less than your material thickness.

release buttons, and slide the adjustment pointer to the
desired setting.

Changing the Mortising Bit
Different mortising bits are available for a variety of Domino
tenon sizes. The DF 700 comes equipped with a 12mm bit;
and 8, 10, and 14 mm bits are available as an option.
WARNING! To reduce the risk of injury from contact
with a moving mortising bit, always unplug the tool
before changing mortising bits or removing the
fence body from the motor housing.
1. Using the provided 12mm wrench, pry up on the fence
body release lever, and slide the fence body off the motor
housing. (The inset photograph on page 6 shows the
fence body and motor housing when separated.)
2. Press and hold the spindle lock button. This stops the
spindle from turning while you loosen the mortising bit.
Supplemental Owner’s Manual 9
3. Loosen the mortising bit by turning it counterclockwise
(standard right-hand thread).
4. Insert a new mortising bit, and start the threads by hand
to avoid cross-threading.
5. Press in on the spindle lock while tightening the bit. Do
not over tighten the bit.
6. Carefully reinstall the fence body onto the motor housing,
and push the fence body in until the latch clicks.
► Make sure there is no sawdust inside the guide tubes
(hollow tubes) before inserting the fence body.
► Be careful not to damage the linear bearings (inner sur-
face of guide tube) when reinstalling the fence body. If
it does not slide on easily, it means the fence is skewed
with respect to the bearings.

Overview, General Notes, and Tips
Because the look and feel of the Domino joiner may already
be familiar to you, or similar to other tools you may have
used in the past, you might be tempted to forego a basic
introduction to using the tool. However, unlike other tools
of similar look and feel, the Domino machine is extremely
precise in its operation. For this reason, it is recommended
that you spend some time practicing using the Domino
joiner before you begin using it for your ne woodworking
projects.
Choosing the Right Domino Tenon Size
Because the Domino system is a form of the classic mortise
and tenon joinery, it should follow much of the same guidelines of mortise and tenon joinery. Here are some guidelines
to assist you in making your choices:
► When the strength of your workpieces is comparable
to the strength of the Domino tenon (e.g. general hard
woods) then the thickness of the Domino tenon should be
Domino Tenon Placement Guidelines
There are no steadfast rules on where tenons should be
placed, especially when they are used for alignment pur-
poses. For edge joining boards, a typical placement might
be 6 to 8 inches apart.
However, when tenons are used to strengthen a joint, you
might be tempted to place the tenons too close together.
This can actually weaken the joint by removing too much of
the substrate material.
► A wide mortise weakens the substrate, so it is better
to have several narrow mortises with uncut space in
between, than it is to have a single wide mortise with
several tenons side-by-side.
► When placing several tenons close together, leave at
least the thickness of a tenon between mortise holes. As
a general rule, this means the minimum tenon spacing
should be about 8 mm to 14 mm, but they can be spaced
much wider.
► When creating stacked mortises for extra thick lumber, an
extension of the “1/3 rule” mentioned above still applies.
Specically, the distance between mortises, and the
For best results, observe the following tips:
► Always secure the workpiece rmly.
► Hold the Domino Joiner rmly by the front handle and
loosely by the rear handle. This keeps control of the joiner
at the front without biasing the main body skewed from
the fence.
► Plunge the mortising bit into the workpiece with a slow
and steady pace.
approximately 1/3 the thickness of the workpieces.
► For softer woods, such as pine, the joint will be stronger
when the tenon is 1/3 or slightly less.
► For plywoods, especially low-grade construction plywoods,
the Domino tenon is much stronger than the surrounding
wood, so it is best to maximize the strength of the substrate by minimizing the thickness of the tenon.
distance between a mortise and the wood surface should
all be equal to (or larger than) the thickness of the tenon.

Plug-It® Power Cord
The Domino joiner comes equipped with a removable Plug-It
power cord. To install the power cord, insert the cord into
the inlet on the tool with the key and keyway of the plug
aligned with the key and keyway of the port. Then twist
the locking ring a full ¼-turn until they lock. Reverse the
procedure to remove the cord.
Notice: Failure to fully lock the plug into the recep-
tacle will damage both the plug and the receptacle.

The Domino joiner is intended to be used with a dust extraction system. Using the machine without dust extraction will
cause it to clog with wood chips.
When installing a Festool dust extraction hose onto the dust
port of the machine, it is easiest to insert the hose at an
angle and then push it on the rest of the way as shown to
the right.
Note: If you have a non-Festool vacuum system
and your vacuum hose does not t the dust extraction port, a Festool vacuum hose will t many other
brands of vacuums.
Using the Stop Pins
On the front of the fence are 3 pair of stop pins. These are
used to register the tool against the edge of the workpiece
or against a previously machined mortise slot, and provide
rapid and precise placement of the tool on the workpiece.
The distances between the locating pin and the center of
the mortise slot are 20, 37, and 50 mm. The pins are spring
loaded, but can also be locked in the retracted position.
To retract a pin, push in on it until it clicks into place. To
release the pins, press the release button on the side of the
fence. There is a release button for the left and right sets of
pins.
The pins are spring-loaded, so it is not necessary to retract
a pin when not in use. However, retracting unused pins will
prevent them from pushing your workpiece away from the
fence.

Using the Base Support Bracket
The base support bracket stabilizes the joiner when mortising on the face of a narrow board as shown to the right. The
base support bracket mounts to the underside of the joiner
with two thumbscrews. Stand the joiner upright on a at
surface when installing the bracket to ensure it is ush with
the front of the joiner.

Assembly
The optional Cross Stops extend the position of the locating pins for wider tenon spacing. These are also adjustable
so the spacing can be tailored to the needs of the specic
application.
Note: The two Cross Stops are specic for right and
left-hand mounting, such that the locking levers point
toward the rear when locked. If you install the adjustable stop pins backward, the locking levers will point
forward when locked, and this will interfere with the
workpiece. If this happens, remove the stop pins from
the outrigger arms and turn them around.
DF 500 versus DF 700 Setup
The new model Cross Stop is compatible with both DF 500
and DF 700 joiners by inverting the stop pin assembly. This
changes the height of the stop pins to line up with existing
mortises. (The previous model will still t the DF 700 joiner,
but the pins won’t line up with existing mortises.)
To invert the stop pin, loosen the clamping knob far enough
to allow the rear clamp to rotate, then rotate the rear clamp
180°, and retighten the clamping knob. The front of the
stop pin assembly indicates which position is for the respective joiner.
Setup
1. With the locking handle rotated toward the front of the
joiner (as shown in the upper photograph) insert the
mounting tab into the slot from below.
2. Turn the locking lever toward the rear to lock the Cross
Stop to the base of the joiner.
3. Loosen the clamping knob on the adjustable stop pin and
slide the pin to the desired position.
4. Before tightening the clamping knob, make sure both
pointers on the locating pin are pointing to the same
measurement on the outrigger arm.
Calibration
To ensure that the stop pins are centered on either side of
the mortise location, they can be calibrated to the Domino
machine to which they are attached. If the stop pins are not
centered about the mortise location of the machine, loosen
the locking setscrew and rotate the eccentric adjuster
slightly. When the screw slot is vertical, the eccentric is in
the neutral position. When the screw slot is horizontal, the
eccentric is in the maximum offset toward or away from the
mortise position. (A stamped “0” indicates the minimum
offset of the eccentric.)
Using the Vertical Alignment Marks
The side of the fence body contains a pair of alignment
marks to indicate the vertical position of the mortising
location. These marks are helpful for identifying the mortise
location when plunging into the face of a large at workpiece. Use these to align the joiner with a pencil line that
represents the desired center of the mortise location.
These can also be used in conjunction with the horizontal
alignment mark on the base of the joiner to position a
mortise at the intersection of two lines.

Applications
Edge Joining Boards
Edge joining boards is a common method for creating wide
boards from a series of narrower boards. The Domino
tenons add strength to the joint and also assist in aligning
the boards to be ush.
For edge joining boards, a series of tenons are placed down
the length of the joint. The rst tenon is used to register the
two boards horizontally, so it is milled at standard width.
The remaining tenons align the boards ush and may be
milled with an oversize width.
Tips for Successful Joining
► Use the stop pins (page 11) for the
rst mortise slot with the mortise width
lever set to the narrow setting (page
8).
► For subsequent mortise slots you can
keep the mortise width at the minimum
setting, but you may nd it easier to set the mortise width
dial to the next widest setting.
► Place the mortise slots 6 to 12 inches apart for standard
joints, but this spacing should be decreased for joining
plywoods or when a stronger joint is needed.
► Instead of marking the mortise placements with pencil
lines, you can use the optional Cross Stops (page 12) to
evenly space the mortises down the length of the boards.
To do this, use the stop pin in the previous mortise slot.

Making Miter Box Joints
Without tenons, miter box joints are fairly weak because the
joint is predominately endgrain to endgrain. Tenons signi-
cantly increase the strength of the joint and make it easier
to assemble and clamp the pieces.
Construction Tips
► For thinner materials, keep the mortise close to the inside
corner. This minimizes the chances for boring all the way
through the workpiece.
► For very thin materials, it may be necessary to shorten
the Domino tenon length as described on page 18.
► For thicker materials, stacked mortises can be used.
Setup and Machining
1. Tilt the fence to the appropriate angle. (Refer to the table
on page 7 for miter angles for multi-sided boxes.)
2. Lower the fence to the desired height. Note that the
mortise should be close to the inside corner to avoid
penetrating through the workpiece.
3. Tip: Before milling the mortise, double check your depth
settings to ensure you don’t cut all the way through.
4. Plunge the joiner as shown below.
5. The stacked mortises are used for thicker stock.
6. Grasp the joiner by the auxiliary handle for best control.

Butt box joints are typically used in general box construction
or for drawer construction. The Domino tenons strengthen
the joint without the need for additional fasteners. The
example below highlights drawer construction, but the same
techniques are used on other types of box construction.
Construction Tips
► For drawer construction with a separate drawer front, the
front and rear of the box should be Captive, as shown
below.
► The drawer front is installed onto the drawer box after
the box has been assembled.
► This increases the strength of the drawer because the
tenons are in shear (perpendicular) to the operation of
opening and closing the drawer.
► The ends of the side boards are concealed by the sepa-
rate drawer front.
► For drawer construction without a separate drawer front,
the Sides should be Captive and the Front/Rear should be
the Caps (the reverse of the image below).
► For cabinet carcase construction, the Top/Bottom of the
carcase should be Captive (also see “Making Carcase Butt
Joints” on page 17).
7. Grasp the Domino joiner by the auxiliary handle, hold
it rmly down to the workpiece, and slowly plunge the
cutter into the edge of the workpiece.
Machining the Cap-Side Mortises
1. Don’t change the fence height from the previous operation. It is used to register the mortise placement from
the edge of the board.
2. If necessary, install the Base Support Bracket as
described on page 11.
3. If necessary, change the mortise depth setting.
4. Clamp the workpiece in a vertical position as shown.
5. When plunging, grasp the Domino joiner at the Base
Support Bracket and hold it rmly against the face of the
workpiece.
WARNING! To reduce the risk of injury from contact
with a moving mortising bit, keep hands clear of the
back of the workpiece in case the mortising bit cuts
all the way through the board.
Machining the Captive-Side Mortises
1. Choose a Domino tenon size to be less than or equal to
1/3 of the board’s thickness.
2. Set the height of the fence so the Domino tenons are in
the center of the board’s thickness.
3. Set the mortise depth according to the instructions on
page 9.
4. Note that if your workpieces are thin, you may need to
offset the tenon from center as shown in the picture on
page 9.
5. Clamp the Captive boards at to your workbench.
6. Align the tenon position using the stop pins (refer to the
picture on page 11).

Butt Joint Frames
When making butt joint frames, such as cabinet faceframes,
use pencil lines to lay out the position of the tenons. Use the
sight gauge on the joiner’s fence to position the joiner over
the pencil line.
For narrow frame stock, the optional Trim Stop can be used
to securely hold the workpiece (shown below).
Trim Stop
For larger frame stock, you may be able to use the stop pins
for setting the mortise position.
Make sure to securely clamp the workpiece to the bench
when mortising a mitered joint.
Cope and Stick (Stile and Rail) Frames
Domino tenons can also be used to strengthen cope and
stick frame construction too (bottom right picture). This is
typically found in raised panel door frames.
It is important to note that the two frame pieces overlap, so
the depth of the mortise needs to be extended. The amount
that each mortise needs to be extended is one-half the
amount of overlap.
Example: A typical stile and rail router bit set has a prole
width (overlap) of 3/8-inch (about 10mm). For a 40mm long
tenon, instead of plunging 20mm deep, you should increase
this to 25mm for both workpieces.
Bench Dog
Mitered Frames
When making mitered frames, position the tenon closer to
the inside corner. This reduces the likelihood of cutting the
mortise all the way through the workpiece.

Using tenoned butt joints is an effective method for constructing a cabinet carcase. The tenons provide a strong
support for each of the horizontal partitions of the cabinet.
The simplicity of this method is that you use the carcase
components for aligning the joiner.
Because the mortises are registered from the base of the
Domino (xed 15 mm distance), the direction that you
tip the shelf (either toward the top or toward the bottom) depends on how thick the shelf is. Use the following
guidelines:
► If the shelf is thick (greater than 30mm), tip it down
with the top-side facing up.
► If the shelf is thin (less than 30mm), tip it down with
the bottom-side facing up.
4. Clamp the two pieces together to prevent them from
moving.
5. With the Domino baseplate resting on the face of the
side-piece, plunge the joiner into the edge of the shelf.
Do not use the fence for height positioning.
Setup and Machining
1. Lay the vertical side pieces on your workbench, and draw
lines across both left and right pieces to indicate where
the shelves will be located. Note that it is easier to avoid
mistakes later on by drawing double lines, with one line
above the shelf and one line below the shelf as shown.
2. For reference, label the top and bottom face of each
shelf. This is so your left- and right-hand mortises are
referenced from the same face of each shelf.
3. Working with one shelf at a time, lay the shelf on top of
the side piece so its edge lines up with the outside pencil
line for that shelf location.
Note: To help you remember how to position the
shelves for mortising, simply stand the shelf up vertically between the pencil lines, and then gently tip it
over so it is laying at against one pencil line.
6. With the joiner standing upright and its baseplate against
the edge of the shelf, plunge downward into the side wall
of the cabinet (see image below).
7. Repeat these steps for each of the shelves.
8. When you repeat this process for the other side wall,
make sure you keep the same side of the shelf facing up.

Making Lock Tenon Joints
Tenon
Holder
Removal
Slot
A locked tenon joint is any type of joint with two or more
tenons at opposing angles. Once the opposing tenon(s) are
inserted, the joint cannot be disassembled. At least one of
the tenons must be exposed so it can be inserted after the
joint is assembled. This is referred to as the Locking Tenon.
There are many variations of a locked tenon joint, but the
simplest involve a mitered corner in a box or at frame. The
miter angle provides an easy reference for the two tenon
angles.
In the example shown to the right, a standard miter joint is
constructed using a large Domino tenon for strength in the
main joint. The locking tenon is a smaller tenon.
The mortise for the locking tenon is milled with the joiner’s
plunge depth set to the full length of the tenon. This mortise
is typically milled after the joint is assembled, but it is possible to mill the mortise in each piece separately.

Shortening a Domino Tenon’s Length
There may be times when you need a large Domino tenon,
but the length of the tenon does not t your application. It
is important to rmly and safely hold the tenon while you
cut it to length.
WARNING! Never attempt to cut a Domino tenon’s
length without using a mechanical holder. Holding
the tenon with your hand poses an extremely seri-
ous risk of personal injury.
To make the simple tenon holder shown to the right, mill a
full-depth tenon slot into the end of a board, and then cut
out a notch in the side of the holder. This notch allows you
to push the shortened tenon out of the mortise slot after it
Tips for Applying Glue
There are many different ways to apply glue to joints; however, how you apply glue can have an impact on the quality
of the joint or the ease of assembly.
► For a longer glue open-time on complex assemblies,
apply the glue generously to the workpieces. The thicker
the glue, the longer the time it will take to skin over
(see image below). Excess glue can be cleaned off after
completion.
► Apply glue to the workpiece face and the mortise slots
before inserting the tenons into the slots.
has been cut to length. Cut the tenon to the desired length
with either a hand saw or miter saw.
► When applying glue for the tenons, you can either apply
glue into the mortise slots, spread a thin layer across the
Domino tenons, or both.
► When the tenon is the primary structure holding the joint
together, you should apply the glue at least to the tenon
(or both). The Domino tenons have small glue pockets
and ridges that will hold glue as the tenon slides into the
mortise slot.
► When applying glue to the mortise slot, take care not to
use too much glue, as there is not enough space for the
excess glue to squeeze out past the tenon.

WARNING! Any maintenance or repair work
that requires opening of the motor or gear housing should be carried out only by an authorized
Customer Service Center (see your dealer for
information on locating a service center).
WARNING! To reduce the risk of electrocution or
other personal injury, always unplug the tool from
the power supply outlet before performing any
maintenance or repair work on the tool.
Routine Maintenance
The Domino tenon joiner does not require much routine
maintenance except for cleaning. For best performance
and long life of the Domino tenon joiner, keep the machine
clean.
► To ensure proper cooling of the tool and motor, the cooling
vents in the motor housing must always be kept clear and
clean.
► Keep the linear rails, guide tubes, and linear bearings
clean and free from sawdust.
► Never store the joiner with the fence body separated from
the motor housing, as this can permit dust and debris to
enter the guide tubes.
► Periodically inspect the mortising bit(s) for damage, wear,
or dullness. Re-sharpen or replace the bits as necessary.
► Never attempt to sharpen the mortising bits yourself. The
mortising bits should be sharpened only by a qualied
sharpening service.
► For best results, only the tip of the bit should be ground,
not the sides.
NOTICE: Do not use compressed air to clean the
motor housing of the tool, as you could inject for-
eign objects into the motor through the ventilation
openings.
NOTICE: Certain cleaning agents and solvents are
harmful to plastic parts. Some of these include, but
are not limited to: Gasoline, Acetone, Methyl Ethyl
Ketone (MEK), Carbonyl Chloride, cleaning solutions
containing Chlorine, Ammonia, and household clean-
ers containing Ammonia.
b. With low-pressure compressed air, blow out any dust
from inside the guide tubes.
c. With a soft cotton cloth, wipe down the interior of the
linear bearings (interior of the guide tubes).
4. With a clean cotton cloth (not the same cloth used previously), apply a coating of light-weight machine oil to the
linear rails and/or linear bearings.
5. Replace the fence body, and with the plunge depth set to
maximum, plunge the joiner in and out several times to
spread the lubricant into the internal linear bearings.
6. Wipe off the excess oil from the linear rails.
Cleaning and Maintenance
1. Blow off the exterior of the machine with low-pressure
compressed air to remove sawdust, but do not blow
air directly into the air cooling vents on the back of the
motor as this can drive debris into the motor.
2. Blow out impacted sawdust from the mortising bit area.
NOTICE: To avoid getting debris inside the guide
tubes, do not remove the fence body from the motor
housing when the joiner is coated with sawdust.
3. With the exterior of the joiner free from sawdust, remove
the fence body from the motor housing and clean the
slide components:
a. With a soft cotton cloth, wipe down the linear rails.

Calibrating the Sight Gauge
Screws
Sight Gauge
Center Line
The horizontal position gauge (also called the sight gauge)
is used for aligning Domino tenons to a pencil mark on the
workpiece. If the gauge is not perfectly centered over the
mortising slot, the two workpieces will not be aligned when
the joint is assembled.
Calibration Procedure
1. Take two pieces of scrap wood, and draw a thin line on
each piece where a tenon is to be placed. You do not
need to be concerned with how the edges line up.
4. Join the two pieces of wood together without glue, and
examine the alignment of the original pencil lines.
5. If the pencil lines are not aligned, loosen the two screws
on the sight gauge and slide the gauge sideways as
noted in the upper image.
Note: The distance between the lines is twice the actual
error. When adjusting the sight gauge, move it only 1/2
the distance between the lines.
Fine Line
2. Set the mortise slot width to the narrow setting (page
8).
3. With the middle line of the sight gauge lined up on the
pencil line, plunge a mortise slot into each piece of wood.
(Do not use the stop pins.)

► Make sure the power switch is off before plugging in the tool.
► Check that the cord is properly plugged into an outlet.
► Make sure the Plug-it connector is properly inserted and fully tightened.
► Make sure the outlet has power. Check the circuit breaker or try another outlet.
► If used with a Festool dust extractor, make sure the selector switch is pointing to “Auto”.
The auxiliary outlet on the dust extractor has power only when the selector is at Auto.
► Inspect the power cord (including extension cords) for damage or missing prongs.
► The motor brushes may have worn and need replacement.
► Clean the linear rails and bronze bearings of the plunge slide, and make sure they are
properly lubricated (refer to the ”Routine Maintenance” on page 19).
► Inspect the linear bearings for damage. Improper insertion of the fence body onto the
motor housing can damage the linear bearings.
► Make sure you hold the Domino joiner rmly in position at the front handle and loosely
at the rear handle while plunging the mortise slot. It is not uncommon for new users to
experience this problem, and is a matter of rening your technique for plunging mortises.
► Plunging too fast can cause the mortise slot to be enlarged. Slow down the plunge rate.
► Make sure the mortise width setting is correct.
► Make sure you are using the correct mortising bit for the size of the Domino tenon.
► Check the mortising bit to ensure it is not bent or has a broken tip. A bent bit will make a
thicker and wider mortise slot than desired.
► The Domino tenons may have shrunk in an overly dry or warm environment. This is
normal wood movement.
► The tenons are intended to be snug tting, and may require a light tap with a mallet to
insert them. This is what affords such high precision for Domino tenon joinery.
► The most common cause for this is that the tenons are stored in a humid environment,
and they have swelled from moisture absorption. Store the tenons in a cool dry environment. (Swollen tenons can be re-dried by heating them to 10 to 15 degrees above
ambient temperature for a short period.)
► The mortising bit may have been improperly sharpened or sharpened too many times.
Replace the bit.
► Make sure the workpiece is securely clamped before plunging.
► Retract the locating pins when not in use.
► Check the calibration of the horizontal position gauge (sight gauge).
► Don’t plunge the mortising bit into the work too fast. This may cause the joiner to move
during the plunge.
► Make sure the friction pads on the front of the joiner are not worn, damaged, or missing.
► Take care not to tilt the joiner while plunging.
► If the mortise slots were registered from the bottom of the baseplate, make sure there is
no dust or debris under the joiner or workpiece.
► Make sure the fence is properly locked at the desired height setting.
► Inspect the fence height adjustment lock to ensure it is not broken (slipping).
► Make sure the fence is set to the correct angle (e.g. 90 degrees).
► Make sure to hold the Domino joiner rmly to the work surface.
► Plunging too slow can cause the mortise slots to be tilted slightly.
► Make sure the proper plunge depth is set.
► Make sure the mortising bit is not broken.
► Make sure the joiner is tight to the face of the workpiece.
► The mortising bit may have been sharpened too many times and is too short.
► Excessive dust may be present inside the linear slide.
► Excessive glue may be present at the bottom of the mortise.
► Plunging speed too fast. Slow down the rate of your plunge.
► Low-grade materials and plywoods will tear out more than solid woods. Decreasing your
plunging speed will improve the results but may not eliminate the problem completely.
► Dull or broken mortising bit.
► The plunge speed is too fast and the bit is not cutting the sides properly. Slow down the
plunge speed.
